Using a Control Supply Module
If you are using a Control Supply Module, apply the 24 V supply directly via the 24 V busbars.
The electronic current limiting function integrated in the Control Supply Module protects the
busbar system when a fault occurs. You can connect additional loads via the 24 V terminal
adapter.
Note
Cables with a cross-section of 2.5 mm
2
If you use cables with a cross-section of 2.5 mm
2
, no additional protection is required on the 24
V side for the following cable types:
● Cables of the XLPE type
● Cables of the EPR type
● Cable with a similar quality and with a thermal stability of up to 90 °C
